Béton brut or "raw concrete" is a naturally porous material that provides many advantages for the design and build of a bathroom. As a waterproof and pressure-resistant material, it is easy to clean, doesn't deteriorate, prevents bathroom fungus and is low maintenance. Attractive as it is functional, concrete is versatile for both on-site furniture and wall coatings, floors and even shower trays. In addition, due to its thermal mass, concrete is an excellent material for floor heating.

Pro Tip: There are a variety of concrete finishes, but for the safety of daily bathroom users, you must add a surface sealer and a certain percentage of traction to avoid slippage.

The private space is usually associated with hiding what goes on inside, allowing people to have certain moments of intimacy. Habitually, bathrooms have been designed for this purpose, reducing openings to a minimum or — sometimes — eliminating them completely.

However, being such an important space within a building, bathrooms have become an object of new exploration for architects. By blurring the limits of privacy — without losing it completely — these spaces are open to the outdoors, allowing the breeze to enter. How does this new experience feel? Check out 30 open bathrooms that play with the feeling of exhibitionism, without fully revealing what is happening inside.
